An Extensive Review on Software Defined Networking (SDN) Technologies

Y.R Medlin Benisha;

Abstract

In the present days, network technologies have always been an important part of success in any communication system. The internet has led to a digital society formation, where from anywhere almost everything is linked and is easily reached. Despite their widespread adoption, traditional IP networks are intricate and very hard to manage. According to predefined policies, it is hard to both configure and reconfigure the network in the case of response to faults, loads and changes. This can lead to problems in effectiveness due to the slow scalable IT infrastructure growth. In this paper, an extensive review on Software Defined Networking (SDN) is presented. Response to problems by providing novel functions to the entire network topology can be easily carried out with SDN. With software defined networking, administrators have the opportunity to abstract the underlying infrastructure of the network for applications and services. After introducing SDN, key concepts and its traditional networking differences, its roots and the activities of standardization are explained in an attempt to expect the future growth of this new model and discuss the main on-going research attempts and challenges. We formulate a scenario classification in which these technologies may contact and observe a significant degradation in the web services performances, in terms of response time and availability. At last we analyse the SDN position as the main enabler of a software-defined environment. SDN present novel networking ideals, simplifying management of network and facilitating evolution in network.
